Check These oot, Min! New helmets from E. Konig!!

[jho]

The only Wiesenau 'Gallic' types with side plumes are the 'F' from Besançon, and the 'I' types from Mainz, Budapest and ex Axel Guttmann collection. The Gallic 'A' type from Eich has holes on the browguard which could have been used for side plumes.

For the sake of completeness: The Weisenau helmet from Straubing, Bavaria also has plume holders (it is not in the Robinson book so I am not sure how you would classify it under Robinson).
